A challenge to improve yourself is the greatest of all challenges you will ever face.

Good becomes better by playing against better, but better doesn't become the best by playing against good.

If you play just to stay healthy and not to win, by all means, keep playing.

Compare the luxuries with a neighbour to feel bad, compare the miseries with a neighbour to feel good.

The information age is converting a human from loving to logical and replacing his peace with the pain.

Quitting because of extreme struggle is sort of success, but quitting because of little inconvenience is insanity.

When I see an arrogant man, I see one less competitor.

If the reason of your sleeplessness is competition, then you will make a successful businessman.

You are a worthy competitor, the best rival I ever encountered, it is an honour to be your opponent, you are better than me at many things, but you cannot beat me at politeness.
